TROUBLESHOOTING - TYPE 50 OVENS
OVEN FAILS TO OPERATE - NO HEAT
1. If oven will not heat, check power supply.
2. Check plug at outer end of power cord. Check com-
plete power cord for continuity. If defective, replace cord
assembly.
3. Disconnect wires from heating element and check
heating element for continuity (access through top of
oven). If defective, replace elements.
4. On type 50A ovens check thermostat for continuity at
ambient temperature (access through top of oven). If
defective, replace thermostat.
OVEN OPERATES - OVERHEATS

ELECTRODE HOLDING
1. Open lid of box and allow approximately 20 minutes
warm-up to drive out any retained moisture.
2. Place only dry electrodes within box. Keep lid closed
but unlatched while plugged into powered receptacle.
ELECTRODE STORAGE
3. When your job is done, the oven should remain con-
nected to its power source. If it becomes necessary to
disconnect from power, keep the lid closed and latched
to provide sealed storage of unused electrodes.
4. Your DryRod® oven has been preset at the factory for
optimum temperature control. The sealed thermostat is
not adjustable, but easily replaced if it fails. Average
stabilized temperature of the oven is 300°F with a full
load (average 250°F empty). A parts list and wiring dia-
grams are printed on the reverse side for your conven-
ience.
